چکیده
We report on a study of polarization-modulation experiments on the 4 → 3 hyperfine component of the D1 transition in Cs vapor contained in a paraffin-coated cell. The laser beam's polarization was switched between left- and right-circular polarization at a rate of 200 Hz. Variations of the transmitted light power were recorded while varying the amplitude of a transverse magnetic field. The power shows electromagnetically induced transparency (EIT) resonances when the atomic Larmor frequency matches a harmonic of the modulation frequency. We made a quantitative study of the resonance amplitudes with square-wave modulations of various duty cycles, and find an excellent agreement with recent algebraic model predictions.

Generation of a chirp-free optical pulse train with tunable pulse width based on a polarization modulator and an intensity modulator.
A simple method for the generation of a chirp-free optical pulse train with tunable pulse width using a polarization modulator (PolM) and a zero-chirp intensity modulator (IM) is proposed and demonstrated. In the proposed system, a light wave with its polarization direction oriented at an angle of 45 degrees with respect to the principal axis of the PolM is polarization modulated by a sinusoida...
متن کاملTransient State Imaging of live cells by Single Plane Illumination Microscopy
Long-lived, photoinduced transient dark states of fluorophores have a great potential for environmental sensing. Transient State (TRAST) Imaging based on time-modulated excitation has recently been shown to provide imaging of the kinetics and populations of these states in biological samples and has been realized for confocal, wide-field and total internal reflection microscopy settings. In thi...
متن کاملQuantum teleportation of a polarization state with a complete bell state measurement.
We report a quantum teleportation experiment in which nonlinear interactions are used for the Bell state measurements. The experimental results demonstrate the working principle of irreversibly teleporting an unknown arbitrary polarization state from one system to another distant system by disassembling into and then later reconstructing from purely classical information and nonclassical EPR co...
متن کاملDouble polarization experiments at intermediate energy
At modern electron accelerators with highly polarized, intense, high duty factor beams double polarization coincidence experiments became feasible with good statistical accuracy. The strong potential towards the precise determination of small nucleon structure quantities is illustrated by two recent examples from MAMI. The measurement of GE in the quasifree reaction D(~e, e′~n)p lead to a new p...

–This work shows that the direct pulse-wide-modulated (PWM) output electric signal, with a duty cycle controlled by light intensity, can be obtained using a circuit that contains a sawtooth voltage generator connected in series with a dc voltage source and a metal (semitransparent gate) oxide semiconductor capacitor (MOS-C) operating in non-equilibrium mode. Amplified output signal presents pos...
